Colin. When I visited Rochester museum, there was a model Sunderland in the display cabinet at the entrance- but that was it! Maybe the other models are in the basement, for they took all my tools, photographs & other memorabilia to put in the basement for a, hopeful, new display of Shorts when they have the space. That will be the day! I only once saw the Mayo & Mercury flying, just before WW2. The Saro SA1 was the first jet(gas turbine) powered flying boat, made by Saro, not Shorts, in Southampton- I think- they probably had a lot of help in the fuselage "planing bottom" from Shorts who had a very long test tank for that purpose. Castle 261.You made a model of the M/M composite in metal? Wow, that needed some doing, congratulations on your fortitude over 2 years. What a great pity they were lost. I made a 1/72nd scale Sunderland in wood-all my models were in wood as plastic die cast were not available during the war. Dad could always get me some offcuts from the Yard! And we had a model club at the County School where we could purchase coloured dope in small amounts for painting the models. Smiffy. They did tell me at R.museum that there were some item at the new council offices in Strood but as I was on a flying visit, I didn't have time to go there, maybe that model is in their basement? What happened to the control column from the Canopus I wonder. I'm sorry that I don't live in the Medway towns now for there is a lot of interest to investigate.( C19 would have scuppered that anyway!)
